Alzheimer's disease: Symptoms, prevention, and dietary impacts

Alzheimer's disease, the most common cause of dementia, is characterized by a progressive decline in cognitive abilities such as memory, thinking, and daily functioning. While often associated with aging, experts warn that dementia is not a normal part of the aging process and can affect individuals even before the age of 65.

Early symptoms that should not be ignored include frequent short-term memory loss, difficulty finding words, confusion, disorientation in familiar places, and challenges with planning or decision-making. The disease is linked to the accumulation of specific proteins in the brain that disrupt signal transmission between cells.

Dietary habits play a significant role in risk reduction. Experts recommend a diet rich in plant-based foods, fish, leafy greens, various fruits, legumes, nuts, whole grains, and omega-3 fatty acids, while reducing saturated fats and ultra-processed foods. Certain spices may also support brain health; for instance, cinnamon contains antioxidants that may inhibit protein buildup associated with Alzheimer's and Parkinson's, while black pepper contains piperine, which helps protect brain cells from damage.
